VOA常速英语:University of Missouri Works to Make a Better MRI

With an MRI patients have to lie often motionless in a long tube.It’s especially challenging for heart patients. It can be very hard, it can be very tiring and there are often very long exams. We schedule them in 90 minutes, an hour and a half slots, which if you’ve even been in an MIR scanner, that’s a long time.
在核磁共振成像中，患者需要躺在一根长管子里一动不动。这对心脏病患者来说尤其具有挑战性。它可能非常难，可能非常累，而且通常有很长的测试时间。我们给的时间是90分钟，一个半小时的时间。如果你曾经做过核磁，那时间真是很长。

In order to get a clear picture, patients have to hold their breath over and over.In general an MRI takes a long time to require a single image and if you’re moving during the acquisition, that image will get blurring.Researchers in the University of Missouri are working to fix that problem with a programme called Heartspeed.With Heartspeed data analysis software pulls out motion information from the magnetic resonance images. This would allow radiologist to see the heart clearly even if the patient is breathing normally.
为了得到一个清晰的图像，病人不得不一次又一次地屏住呼吸。一般来说，核磁共振成像需要很长时间才能得到单个图像，如果在获取过程中移动，图像会变得模糊。密苏里大学的研究人员正在通过一个名为“心跳速度”的项目来解决这个问题。利用心率数据分析软件从磁共振图像中提取运动信息。这样即使病人呼吸正常，放射科医生也能清楚地看到心脏。

We find that we could separate breathing motion from the heart motion quite well using the software and we thought we should try to start applying this to really patient data.
我们发现我们可以用这个软件很好地把呼吸运动和心脏运动区分开来，我们认为应该开始把这个应用到真正的病人数据中。

The goal, a more comfortable scan for patient who could breathe in a normal pace without repeated breath holds.Scans will also be much shorter, just fifteen to thirty minutes.Patients will benefit because it would be easier for them to do the exam,hopefully the radiologist who reads it or with cardiologist who reads the MIR will benefit because the images will be much better.The researchers estimate that the Heartspeed technology will be available for clinical use within five years.
目标是，使患者能够正常呼吸而无需重复屏息，并且让扫描更舒适。扫描时间也会短得多，只有15到30分钟。病人会受益，因为他们更容易做检查，希望读它的放射科医生或读MIR的心脏病科医生会受益，因为图像会更好。研究人员估计，这项心跳加速技术将在五年内用于临床。
